Abstract
An oil conduit connecting type anti-drop buffering safety device comprises an upper joint, a central tube, an object containing basket, a disc chuck and a buffering mechanism, characterized in that, one end of the central tube is connected with the upper joint, the other end of the central tube is connected with the buffering mechanism, the object containing basket is mounted outside the central tube, the lower part of the object containing basket is fixed with the buffering mechanism, the disc chuck is mounted at the lower part in the central tube. The utility model has a bottom object containing basket, which can avoid the object dropping into a tail tube, when the pipe column falls off, the buffering mechanism can buffer and protect the downhole pipe column, when the fallen pipe column is clamped for the salvaging processing, but is not pulled out, the sheared pin bolt in the utility model can be conveniently pulled off, the pipe column higher than the object containing basket is raised up from the ground for preventing the clamping accident and improving the construction success rate, the utility model can be widely applied to the petroleum extraction technique.
Description
One, technical field
The utility model relates to the oil exploitation downhole tool, particularly a kind of anti-lost buffer safety device of oil pipe interconnection system that is applied to down-hole string.
Two, background technology
In the oil exploitation, high-inclination directional well and horizontal well completion sleeve pipe generally adopt the liner completion mode that hangs, this tubular column structure, exist following shortcoming or deficiency: 1. in flow string rountrip process, when small articles such as screw fall well, fall in the tail pipe easily, cause in the tail pipe measure operation to be obstructed, it is big to salvage this type of trouble of lost tool in hole difficulty, and success rate is low.When 2. the tubing string case accident took place, extension hanger was very easily impaired, even caused heavy repair task or major accident such as scrap.
Three, summary of the invention
The purpose of this utility model provides the anti-lost buffer safety device of a kind of oil pipe interconnection system; adopt the utility model to be connected in the mode of flow string bottom; both can canvass the smallclothes junk; avoid it to fall in the tail pipe; can play buffer protection function to down-hole string again, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
The anti-lost buffer safety device of oil pipe interconnection system described in the utility model comprises top connection, central tube, pocket thing basket, floral disc and buffer gear.Described central tube one end is connected with top connection, and the other end is connected with buffer gear, and pocket thing basket is installed on outside the central tube, and its underpart and buffer gear fix, and floral disc is installed on bottom in the central tube.
Wherein, described buffer gear comprises that the tube connector, pocket thing basket lower end and the tube connector that are connected with the central tube lower end fix cuts off pin, be installed on the soft metal ring and the elastic buffering pad of tube connector bottom and pocket thing basket bottom in turn.Described tube connector is that top is provided with outer up and down shoulder, and the lower end is provided with the tubular structure of bottom shoulder.Described pocket thing basket is by cutting off on the outer up and down shoulder that pin is fixed in tube connector top.The described pin of cutting off is at least one.Described pocket thing basket is provided with centre bore, up big and down small reducing tubular element for its wall is provided with uniform intercommunicating pore, lower end.The upper and lower side of described elastic buffering pad respectively is equipped with a soft metal ring.
The utility model has the following advantages compared with prior art:
1, is connected the flow string bottom and can canvasses the smallclothes junk, avoid junk to fall in the tail pipe;
Buffer protection function can play to down-hole string in protecting against shock mechanism when 2, the generation tubing string came off; the tubing string that comes off is met card and is salvaged to handle and pull out again when motionless at the extension hanger place; can easily the pin of cutting off in the utility model be broken; the above tubing string of pocket thing basket is proposed ground; meet the card accident, raising construction success rate to prevent tubing string.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the utility model embodiment.
Five, the specific embodiment
Consult accompanying drawing, the anti-lost buffer safety device of a kind of oil pipe interconnection system comprises top connection 1, central tube 2, pocket thing basket 3, floral disc 5 and buffer gear.Central tube 2 one ends are connected with top connection 1, and the other end is connected with buffer gear.Pocket thing basket 3 is installed on outside the central tube 2, and its underpart and buffer gear fix.Floral disc 5 is installed on bottom in the central tube 2.
Buffer gear comprises that the tube connector 6, pocket thing basket 3 lower ends and the tube connector 6 that are connected with central tube 2 lower ends fix cuts off pin 7, be installed on the soft metal ring 8 and the elastic buffering pad 9 of tube connector 6 bottoms and pocket thing basket 3 bottoms in turn.Tube connector 6 is outer up and down shoulder for top is provided with, and the lower end is provided with the tubular structure of bottom shoulder.Pocket thing basket 3 is by cutting off on the outer up and down shoulder that pin 7 is fixed in tube connector 6 tops.Cut off pin 7 and be at least one.Pocket thing basket 3 is provided with centre bore, up big and down small reducing tubular element for its wall is provided with uniform intercommunicating pore 4, lower end.The upper and lower side of elastic buffering pad 9 respectively is equipped with a soft metal ring 8.
The installation quantity of cutting off pin 7 is looked the size decision of its diameter, installs one at least, is used for axial restraint tube connector 6 and pocket thing basket 3.The upper surface of tube connector 6 top cylindrical lower shoulders closely contacts with cutting off pin 7, under the tubing string towards the time cut off pin 7 and can move to tube connector 6 top cylindrical upper shoulders, to eliminate tubing string to cutting off the downward impact force of pin 7.
During on-the-spot the use; the utility model is connected the flow string bottom; can canvass the smallclothes junk; avoid junk to fall in the tail pipe, buffer protection function can play to down-hole string in protecting against shock mechanism when tubing string taking place coming off, and the tubing string that comes off is met card and salvaged to handle and pull out again when motionless at the extension hanger place; can easily the pin 7 of cutting off in the utility model be cut off; the above tubing string of pocket thing basket is proposed ground, meet the accident that card can not pull out, improve the construction success rate to prevent tubing string.
